The 1974 Super Outbreak was the second-largest tornado outbreak on record for a single 24-hour period, just behind the 2011 Super Outbreak. It was also the most violent tornado outbreak ever recorded, with 30 F4/F5 tornadoes confirmed. From April 3–4, 1974, there were 148 tornadoes confirmed in 13 U.S. states and the Canadian province of Ontario. In the United States, tornadoes struck Illinois, Indiana, Michigan, Ohio, Kentucky, Tennessee, Alabama, Mississippi, Georgia, North Carolina, Virginia, West Virginia, and New York. The outbreak caused roughly $843 million USD in damage, with more than $600 million occurring in the United States. The outbreak extensively damaged approximately 900 sq mi (2,331 km2) along a total combined path length of 2,600 mi (4,184 km). At one point, as many as 15 separate tornadoes were occurring simultaneously.
This article lists various tornado records. The most "extreme" tornado in recorded history was the Tri-State tornado, which spread through parts of Missouri, Illinois, and Indiana on March 18, 1925. It is considered an F5 on the Fujita Scale, even though tornadoes were not ranked on any scale at the time. It holds records for longest path length at 219 miles (352 km), longest duration at about 3+1⁄2 hours, and it held the fastest forward speed for a significant tornado at 73 mph (117 km/h) anywhere on Earth until 2021. In addition, it is the deadliest single tornado in United States history with 695 fatalities. It was also the third most costly tornado in history at the time, but has been surpassed by several others when non-normalized. When costs are normalized for wealth and inflation, it still ranks third today.

Oklahoma City lies in a temperate humid subtropical climate, with frequent variations in weather daily and seasonally, except during the consistently hot and humid summer months. Consistent winds, usually from the south or south-southeast during the summer, help temper the hotter weather. Consistent northerly winds during the winter can intensify cold periods. Oklahoma City's climate transitions toward semi-arid further to the west, toward humid continental to the north, and toward humid subtropical to the east and southeast. The normal annual mean temperature is 61.4 °F (16.3 °C); the coolest year was 1895 with a mean of 57.9 °F (14.4 °C), while the warmest 2012 at 64.1 °F (17.8 °C). Precipitation averages 36.52 inches (928 mm) annually, falling on an average 84 days, with the warmer months receiving more; annual precipitation has historically ranged from 15.74 in (400 mm) in 1901 to 56.95 in (1,447 mm) in 2007. The sun shines about 69% of the time, with monthly percent possible sunshine ranging from 60% in December to 80% in July.
A destructive series of four tornadoes hit the Southeastern United States during March 3-4, 1966. The worst event was a violent and long-lived F5 tornado, dubbed the Candlestick Park tornado after the name of a recently opened Jackson, Mississippi shopping center that was leveled by the storm. The storm would bring catastrophic damage in Mississippi and Alabama along a 202.5-mile (325.9 km) track. The outbreak killed 58, injured 521, and caused $75.552 million in damage.
The Tornado outbreak of June 7–8, 1984 was a significant severe weather and tornado event that took place across the central United States from North Dakota to Kansas on June 7–8, 1984.

Tornadoes are more common in the United States than in any other country or state. The United States receives more than 1,200 tornadoes annually—four times the amount seen in Europe. Violent tornadoes—those rated EF4 or EF5 on the Enhanced Fujita Scale—occur more often in the United States than in any other country.
The state of Alabama is classified as humid subtropical (Cfa) under the Köppen climate classification. The state's average annual temperature is 64 °F (18 °C). Temperatures tend to be warmer in the state's southern portion with its proximity to the Gulf of Mexico, while its northern portions, especially in the Appalachian Mountains in the northeast, tend to be slightly cooler. Alabama generally has hot, humid summers and mild winters with copious precipitation throughout the year. The state receives an average of 56 inches (1,400 mm) of rainfall each year and experiences a lengthy growing season of up to 300 days in its southern portion. Hailstorms occur occasionally during the spring and summer here, but they are seldom destructive. Heavy fogs are rare, and they are confined chiefly to the coast. Thunderstorms also occur year-around. They are most common in the summer, but they are most commonly severe during the spring and late autumn. That is when destructive winds and tornadoes occur frequently, especially in the northern and central parts of the state. Central and northern Alabama are squarely within Dixie Alley, the primary area in the U.S. outside the Southern Plains with relatively high tornado risk. Alabama is ranked second in the U.S for the deadliest tornadoes. Hurricanes are quite common in the state, especially in the southern part. Major hurricanes occasionally strike the coast, such as Hurricane Frederic in September 1979 and Hurricane Ivan in September 2004; both storms resulted in significant to devastating damage in the Mobile area.
The 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, taking place in the Southern, Midwestern, and Northeastern United States from April 25 to 28, 2011, leaving catastrophic destruction in its wake. Over 175 tornadoes struck Alabama, Mississippi, and Tennessee, which were the most severely damaged states. Other destructive tornadoes occurred in Arkansas, Georgia, Kentucky, Louisiana, New York, and Virginia, with storms also affecting other states in the Southern and Eastern United States. In total, 360 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada. Widespread and destructive tornadoes occurred on each day of the outbreak. April 27 was the most active day, with a record 216 tornadoes touching down that day from midnight to midnight CDT. Four of the tornadoes were rated EF5, which is the highest ranking on the Enhanced Fujita scale; typically these tornadoes are recorded no more than once a year.
The 2011 Hackleburg–Phil Campbell tornado was an extremely deadly, violent, and long-tracked EF5 wedge tornado that devastated several towns in rural northern Alabama, before tearing through the northern suburbs of Huntsville and causing damage in rural portions of southern Tennessee on the afternoon and early evening of April 27, 2011. It was the deadliest tornado of the 2011 Super Outbreak, the largest tornado outbreak in United States history. The tornado reached a maximum width of 1.25 miles (2.01 km) and was estimated to have had peak winds of 210 mph (340 km/h). The tornado killed 72 people, making it the deadliest tornado in Alabama history, and injured at least 145 others. At the time, it was the deadliest tornado to strike the United States since the 1955 Udall, Kansas, tornado.
This page documents the tornadoes and tornado outbreaks of 1974, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.
